sparc: rename piggyback_32 to piggyback

2011-01-05T03:25:06+00:00

Now that we use the same piggyback for 32 and 64 bit
we can drop the _32 suffix.
Include some trivial unification in the Makefile
now that 32 and 64 bit can share the same piggyback command.

sparc: fix tftpboot.img for sparc64 on little-endian host

2011-01-05T03:25:06+00:00

piggyback_32 adapted to support sparc64:
- locating "HdrS" differs for sparc and sparc64
- sparc64 updates a_text, a_data + a_bss in the final a.out header

Updated Makefile to use piggyback_32 for sparc64.
Deleted the now unused piggyback_64.c

piggyback_32.c is host endian neutral and works on both
little-endian and big-endian hosts.
This fixes a long standing bug where sparc64 could not
generate tftpboot.img on a x86 host.

sparc: add $BITS to piggyback arguments

2011-01-05T03:25:05+00:00

Add new option to piggyback that identify if this is
for 32 or 64 bit.
Use this information to determine the alignment used.

sparc: remove obsolete ELF support in piggyback_32.c

2011-01-05T03:25:05+00:00

As we always convert to a.out there is no need to
support ELF.

Removing ELF support because:
- it is not used
- it simplifies code to support a.out only

sparc: additional comments to piggyback_32.c

2011-01-05T03:25:04+00:00

While reverse engineering the functionality of piggyback
I missed that the code was actually commented.
So I added a few comments.

sparc: use _start for the start entry (like 64 bit does)

2011-01-05T03:25:04+00:00

We use "_start" in 64 bit - do the same in 32 bit.
It is always good to be consistent.
